Okay, let’s tackle this. So John McShane has experience in fire protection design and sprinkler systems, which are in demand. He worked at Conti Fife Protection and Conti Fire Protection, which suggests a level of expertise. Location is Livonia, Michigan, which is a mid-sized city in the US. Fire protection professionals with similar experience and skills might charge around $100–$200 per hour. Considering his experience and skills, I estimate his hourly rate to be around $125, which is at the lower end of the range.
